When an application is created, it has multiple parts, and all the users cannot be allowed to access the entire application. Thus, the requirement arises to provide restricted access to different users on different parts of the application. In other words, we need rules custom-made for various users. This use case is solved using “user roles and privileges.”
Spring security makes it easier to build these rules using its roles and privileges feature. The role represents a high-level role in the system (e.g., ADMIN, MANAGER, etc.). Each position can have low-level privileges. And, the privileges define the low-level authority for a Role (e.g., ADMIN can read/write/delete, but MANAGER can only read/edit). During registration or creation of the account, these roles and privileges can be assigned to the users.
There are multiple ways to design the spring security roles and permissions, and you can learn them online, at your own pace and comfort, without even spending money. Check out the courses on knowledge2life right now!
